Definitions

  • the present invention relates to a train control system.
  • JP 2017-87978 A discloses an invention that supports the operation of a train by reducing the burden on an operator particularly when the train passes through a railroad crossing by "a train operation support system including: an on-board device mounted on a train traveling on a track; an image pickup device that picks up an image of an inside of a railroad crossing provided on the track and generates image information; a ground device that wirelessly transmits the image information or information based on the image information to the on-board device as in-railroad crossing information; and a display device that is provided in a cab of the train and displays the in-railroad crossing information received from the ground device by the on-board device when the train reaches a predetermined position before the railroad crossing".
  • the ground device collects in-railroad crossing information (image) captured by the image pickup device. Then, the collected in-railroad crossing information is transmitted from the ground device to the on-board device and displayed on the display device of the on-board device, so that the operator can check the situation in the railroad crossing by this display.
  • the remote control of the train from the ground is centrally managed in accordance with the presence or absence of the obstacle or a hindrance. Therefore, the invention in PTL 1 has only an effect that an operator can display and check the in-railroad crossing information (image) on the vehicle.
  • the fact is that, when the train passes through a place where the operator cannot see, the operator sounds a horn or the like to inform the surroundings of the passage of the train. Even if the operator can display and check the situation in the railroad crossing with an image, it is difficult for the operator to reliably detect the presence or absence of the obstacle or hindrance only with the image information. Furthermore, means for giving information to the operator is not considered for a situation in a place such as a curve with poor visibility other than a railroad crossing and a station platform.
  • an object of the present invention is to provide a technique capable of displaying and checking an image and position information of a monitoring camera on an on-board side in a manner that the monitoring camera and a sensor (such as a millimeter wave or a LIDAR) is installed around a railway track on which a train travels, particularly at a place where an operator cannot see, for example, a curve, a railroad crossing, a station platform, or the like, so as to detect an obstacle or a hindrance on a ground side based on a camera video (or a camera image) obtained by the monitoring camera or the sensor, and, when an obstacle or a hindrance can be detected, the camera video (or an obstruction detection result) and a position (equipment ID) of the monitoring camera that captures an image of the obstacle or the hindrance are transmitted to the on-board side.
